if you in the tech section under carbs specs i shows where the brass with paint on it plug is - on the right forward - atleast I think theres picture - let me go look

Ok, thanks, i saw that little plug, but thought it was
too small to be hiding a mix screw.   The plug on mine
has a tiny hole in the center of it.

I found a small sheet metal screw and an appropriate bit to do this.  After I drilled through the brass plug, I tightened the screw in the hole pretty well. THen I use a pair of vice-grips to grab the plug and yanked it right out. Shouldn't be hard to remove, you just have to get a hold on it. .
